Application filed January 13, 1906. Serial No. 295,520.

To all whom it mayconcem:

Be it known that I, FELIX JULES CHARY, a citizen of the Republic of France, and resident'of Paris, France, have invented a new and useful Imiprovement in or Relating to Elastic Tires or Vehicles, which improve ment is fully set forth in the following speci fication.

, Elastic tires for vehicle wheels have already been lproduc'zed,. com rising a series of rubber bloc s of rectangu ar shape secured to the rim by means of metal frames. These blocks, arranged longitudinally one after an- .other, are non-continuous or present between the car.

them s aces which produce strong vibrations' w ich injuriously afiect all the parts of This invention relates to a construction of i an elastic tire which obviates the above drawback. Therefore a construction has been designed. in which are used blocks in the shape of a parallelogram, secured to the rim, and arranged diagonally relatively to the wheel. In this way the arrangement of the blocks enables one block to begin to act while 7 the preceding one is stillin contact with the ground, so that the same advantages are obtained as with a tire '-with double series of elements, or with acontinuous tire. Moreover, the drawbacks of. the continuous. tire, more particularly heating, are avoided, and repairs can be effected block by block.

In order to render the descri tion as clear as possible, a construction of t e elastic tire according to this invention is illustrated,

way of example, in the accompanying drawl igurel' is an elevation of a block or elementof a tire, Fig. 2 is a plan of the frame 6. [Figs 3'and 4 are sections of the block shown in Fig. 1, on the'lines A A and B B of. Fig. 2, Figs. 5, 6 and 7 are cross-sections vof the frame on the lines 0 O D D and E E of Fig.2, Fig. 8 is a perspective view of a wheel with a tire with a double series of staggered or overlapping elements.

The block 0 (Figs. .1, 3 and 4) of the sha e already described, is secured to the rimy means of a metal frame 6, the recessed portion of which has the exact shape of'the block.

he block itself is provided with a projecting flange a which engages with a groove 11 provided on all four under sides of the frame b.

under the frame'being sufficient to prevent the block' from escaping or being wrenched out. However, way of precaution, when it is. a; question of square or rectangular blocks for arrangement in double series, or of blocks in the shape of aparallelogram arranged diagonally in a single series, each .frame is provided with inwardly projecting tongues or projections b which engage with the block in the manner shown in Fig." 2,

their, object being to pro erly maintain the block in its place in the rame, which might have the tendency of becomingcrushed in the portion of the frame o posite to the direction of travel of the vehicle. The fixing boltsare preferably arranged atthe point of these tongues or projectlon'szas shown in Fig. 8.

' As shown in Figs. 2 and the sides of the,

frame 6 which are arallel to the sides'of the wheel are provide with downwardly=turned flanges which inclose the flange c of the block at its outer edge. Fig. 4 shows that the other sides of the. frame are not provided with these downwardly-turned flanges, but one of these sidesis provided with a lateral flange b which is adapted to fit over the frame of the adjacent block, asshown in Fig. 8. Fig. 6

shows the side of the frame which fits under the flange b of the adj acentframe, theform of said flange being indicated in Fig. 7 as well asFig.4. I

-,Having thus described my invention, I cl'aimz- Ina tire for vehicle-wheels, the combination, withthe rim, "of a plurality of frames of parallelogrammic f'orm secured in said rim independently of each other, each frame hav-- ing a groove at its .under part on all sides and inwardly-proj ecting tongues 'intermediatcly of the length of all of the sides, and tread-v specification in the presence 7 of two sub-- blocks secured within said frames by means scribing Witnesses.

of base-flanges which extend beneath said tongues and into said grooves, th e grooyes FELIX JULES CHARY' 5 or spaces between adjacent blocks extending Witnesses:
